TIP (temporary import permit)

Trying to find out if a new one year TIP can be obtained in lLazaro Cadenas or is a border run imperative? I can't find a new or used car here that works for me so will become a temporal for four more years and I can fly to Texas and get the "30 day" temporal visa to be completed here but it doesn't address how to keep my car legal. The Aduana website is extensive but I cannot find out where they may or may not address this issue.
